Subject: [PATCH] fix(create): show helpful error for unknown vite: templates

Fixes issue #1128 where 'vp create vite:<unknown>' crashes with ENOENT.

Added validation for builtin template names in the create command. When
an unknown 'vite:' prefixed template is provided, the CLI now displays
a clear error message listing the valid builtin templates instead of
crashing with an ENOENT error.

Valid builtin templates are:
- vite:monorepo
- vite:application
- vite:library
- vite:generator
